Looks like these are the only calls to substevalchar(), so perhaps
the changes could be made internal to that.  If the test for
errflag within substevalchar() is, as I presume, there simply because
something later in the function will fail if errflag is non-zero, that
might be the point to clear it.  Then the function can return the
error state at the end of the function just before it restores errflag.
